il! or. 'the other hand, the reel 3 is to talle up iilm too fest, the erm -pull downward, thus temporarily uither quantity of lilm to the the' same manner as erm. 72 and held by the spring 7l. Arm 8l, however, has three branches and a can or magazine 86 is fas'- tened to the( three branches .and thus is 'free to rotate around the shaft 65. One of the branches oli erm Se carries two rollers 85 which have thesame function and method` of operation as roller 73. The magazine 86 is provided with a slit in side 'opposite the rollers 85, through which 'the film passes from the reel 37 inside' the magazine, to the feeding mechanism.

8? is a swinging cover for the magazine 86, which is: closedaiter the reel 37 is in place. ln operation, the arm 84 swings around the shaft. 65 precisely the same as does arm 72, as previously described, and since the magazine S6 moves with 84C, the

slot in the side thereof always occupies the same relation-to the rollers 85 and 'the pessage o'the film from the magazine to the rollers is not atected by the changing positions of the arm 8s, as would be the case 7g" if the magazine were fixedly mounted. l

The projecting lens 38 and the stereopti con lens 39 are each fitted inthe usual cylind `ical mount. l have provided a simyble form of adjustment for focusing purposes for these lenses. l provide a tubular mem!- ber 77 provided with a curved opening T78 1n .its `wall, through which progects a handle or stem 88 attached to the lens mount. This stem vis threaded and over it is pls-.ced a threadedsleeve 79, as shown in section in Fig, ily,y rotating the lens mount hy means of the handle 79, the engagement of the sL 88 with the slot 78 causes the lens to he moved toward or away from the ex.- posure opening 50 tofocus the. picture. l After the lens is focused, it is clamped position by turning the handle 79, which hecause of the screw thread on 88, binds the y lens mount in the tubular member ZPL eo 'helamp house 25 is mounted on the hase 8G by four shaped links 81, one of which. has attached to it a spring-seated hell 82, co operating with indentations in a plate 83 in the hase SO to hold the lamp houseyieldingly e in predetermined positions. It will be thatvhen the lamp house is moved, it is forced to travel in a circle with the axis of the lamp house always parallel to its original position, and therefore always parallel to the axis of the projecting lens. As shown in Figs. 2 and 16, I have provided the oircular member 83 with three depressions, so as to locate the lamp house properly either in operative alinement with the motion picture lens, or with the stereopticon lens, or to hold it 'farthest removed from these lenses and. 'the exposure plate 29 Vso es to give free access tothe mechanism when threading the ilm.

'While l have illustrated and described my invention as a device using a reel of nlm, it may Lalso be used eliciently with the .film made up as a continuous band, in Which ease the bracket 3G and the belt Z6 would he removed. When a continuous band oi film is used, there Will heno reversal of the motion of the mechanism, since shifting from one row of picturestoA the other would occur upon 'the completion of one turn of the hand.
